Originally posted by luftfluss I guess I just wince internally seeing that single point of failure at the tripod foot... over the years I've read a few sad tales of straps or attachments failing, resulting in catastrophe - the actual metal broke. It would be nice to have a small auxiliary strap from where your strap attaches at the tripod foot to the body. My Tamron 400/4 has two lug rings to which I attach my Peak Design strap, and I appreciate the redundancy.
If I were more of an adventurer, I'd probably go with a full-on sling.
Of course, most likely everything is fine, and I'm just turning into my mother.
Yeah - there have been a couple reports of the 150-450 foot failing at the attachment to the collar - but that seems to be more when the was a dynamic force applied, not just when static. I think that's the only real possible failure point in the system as I have it.
Strap lugs would be nice to have... though with your setup, as I understand the PD strap is a regular strap with two attachment points - so if one of your attachment points failed, wouldn't the set up still fall? Or I guess if you have a quick enough reaction you may catch it.
But now you've got me thinking of a secondary safety tether of sorts, I'll have to think of a way to do so - as attaching a cord to the body doesn't seem very practical when I'm often rotating the collar in use. Not to mention the force applied to the body attachment point if the tripod foot fails - there would be some slack from the rings to the body, which would result in a sudden stop, possibly tearing/damaging the point on the body (better than the lens hitting the ground I suppose).
Maybe some sort of webbing loop that goes around the lens body by the tripod mount - should be fine if it's not the main system of carrying, but an emergency back up?

Agreed! There's no reason not too really, they can be fairly small and out the way, and it really wouldn't be anything in the way of production cost.
